4 Applications & Materials Ferrites are dense, homogenous ceramic structures made by mixing iron oxide with oxides or carbonates of one or more metals such as zinc, manganese, nickel or magnesium. They are pressed, then fired in a kiln at 1093 C, and machined as needed to meet various operational requirements. Ferrite parts can be easily and economically molded into many different geometries. Many diverse materials are available, providing many choices of desirable electrical and mechanical properties. Magnetics ferrite cores are manufactured for a wide variety of applications. Magnetics has the leading MnZn ferrite materials for power transformers, power inductors, wideband transformers, common mode chokes and many other applications.

6 Toroids 2.54mm 9.53mm TOROIDS Ferrite toroids offer high magnetic efficiency as there is no air gap, and the cross sectional area is uniform. Available in many sizes (O.D.s from 2.54 mm to 140 mm) and materials (permeabilities ranging from 900 to 10,000), this section lists common sizes. For additional sizes contact Magnetics Sales. Toroid mounts and headers are available in a range of sizes. Typical applications for high permeability toroids (J and W materials) include common mode chokes, broadband transformers, pulse transformers and current transformers. L, R, P and F material toroids are excellent choices for high frequency transformers. Special sizes in J material are available for Ground Fault Interrupter applications.

16 E, I Cores 12mm 35mm E CORES E cores are less expensive than pot cores, and have the advantage of simple bobbin winding plus easy assembly. E cores do not, however, offer self-shielding. Lamination size E cores are available to fit commercially offered bobbins previously designed to fit the strip stampings of standard lamination sizes. Metric and DIN sizes are also available. E cores can be pressed to different thicknesses, providing a selection of cross-sectional areas. Bobbins for these different cross sections are available. E cores can be mounted in different directions and, if desired, provide a low profile. Printed circuit bobbins are available for low profile mounting. Typical applications for E cores include differential, power and telecom inductors, as well as, broadband, power, converter and inverter transformers.

30 Planar E, I Cores 14mm 36mm PLANAR E, I CORES Planar E cores are offered in all of the IEC standard sizes, as well as a number of other sizes. The leg length and window height (B and D dimensions) are adjustable for specific applications without new tooling. This permits the designer to adjust the final core specification to exactly accommodate the planar conductor stack height, with no wasted space. Clips and clip slots are available in many cases, which is especially useful for prototyping. I-cores are also offered standard, permitting further flexibility in design. E-I planar combinations are useful to allow practical face bonding in high volume assembly, and for making gapped inductor cores where fringing losses must be carefully considered due to the planar construction. Differential inductors and DCDC, ACDC converter are typical applications for planar cores. 28 Planar E, I Cores - MAGNETICS NOMINAL A L (MH/1000T) TYPE/SIZE ORDERING CODE L R P F E 14/2.5/15 0_41425EC 780 1,653 1,595 1,765 E 14 C C_41434EC 600 1,327 1,399 1,563 I 14 C C_41434IC 780 1,504 1,580 1,749 E 18 C C_41805EC 1,500 3,244 3,430 3,853 I 18 C C_41805IC 1,800 3,606 3,801 4,241 E 18 F_41805EC 1,550 3,244 3,430 3,853 I 18 F_41805IC 1,800 3,641 3,837 4,278 E 22/4/7 0_42107EC 3,448 3,173 3,810 I 22/4/7 0_42107IC 1,480 E 22 C C_42216EC 2,300 5,066 5,387 6,131 I 22 C C_42216IC 2,900 5,956 6,506 7,327 E 22 F_42216EC 2,400 5,066 5,387 6,131 I 22 F_42216IC 2,900 6,207 6,568 E 32 C C_43208EC 6,521 6,918 7,834 I 32 C C_43208IC 7,321 7,745 8,711 E 32 F_43208EC 3,200 6,700 6,918 8,744 I 32 F_43208IC 3,700 7,321 7,745 8,711 E 36/6/18 0_43618EC 6,678 7,090 8,039 I 36/3/18 0_43618IC 7,303 7,736 8,729 MAGNETIC DATA Weight (grams per set) TYPE/SIZE ORDERING CODE l e (mm) A e (mm 2 ) Amin(mm 2 ) V e (mm 3 ) WaAc (cm 4 ) E 14/2.5/15 0_41425EC E 14 C C_41434EC I 14 C C_41434IC E 18 C C_41805EC I 18 C C_41805IC E 18 F_41805EC I 18 F_41805IC E 22/4/7 0_42107EC I 22/4/7 0_42107IC E 22 C C_42216EC , I 22 C C_42216IC , E 22 F_42216EC , I 22 F_42216IC , E 32 C C_43208EC , I 32 C C_43208IC , E 32 F_43208EC , I 32 F_43208IC , E 36/6/18 0_43618EC , I 36/3/18 0_43618IC ,

36 PQ Cores PQ CORES PQ cores are designed specifically for switched mode power supplies. This design provides an optimized ratio of volume to winding area and surface area. As a result, both maximum inductance and winding area are possible with a minimum core size. The cores provide maximum power output with minimum assembled transformer weight and volume, in addition to taking up a minimum amount of area on the printed circuit board. Assembly with printed circuit bobbins and one piece clamps is simplified. This efficient design provides a more uniform crosssectional area; thus cores tend to operate with fewer hot spots than with other designs.

38 Pot Cores POT CORES The pot core shape is a convenient means of adjusting the ferrite structure to meet the specific requirements of an application. Both high circuit Q and good temperature stability of inductance can be obtained with these cores. Pot cores, when assembled, nearly surround the wound bobbin. This selfshielded geometry isolates the winding from stray magnetic fields or effects from other surrounding circuit elements. Both plain and printed circuit bobbins are available, as are mounting and assembly hardware. Typical applications for pot cores include; differential inductors, power transformers, power inductors, converter and inverter transformers, filters, both broadband and narrow transformers and telecom inductors.

47 Other Products from Magnetics POWDER CORES Powder cores are excellent as low loss inductors for switched-mode power supplies, switching regulators and noise filters. Most core types can be shipped immediately from stock. Kool Mµ powder cores have a higher energy storage capacity than MPP cores and are available in five permeabilities from 26µ through 125µ. Kool Mµ toroids are available in sizes identical to MPP cores, and extremely large (>4.0 or mm) toroids/shapes are possible with interlocking Kool Mµ segments. This material is also available in a number of E-core sizes. Permeability for Kool Mµ E-cores is from 26 to 90 and sizes are tooled ranging from the EF 12.6 to the 160LE size. Kool Mµ blocks and U cores are also available. Molypermalloy powder cores (MPP) are available in ten permeabilities ranging from 14 through 550, and have guaranteed inductance limits of ±8%. Insulation on the cores is a high dielectric strength finish not affected by normal potting compounds and waxes. Thirty sizes include I.D.s from (1.78 mm) to (49.2 mm) and O.D.s from (3.56 mm) to (77.8 mm). Standard cores include either temperature stabilized (as wide as -65 C at 125 C for stable operation) or standard stabilization. High Flux powder cores have a much higher energy storage capacity than MPP cores and are available in six permeabilities from 26µ through 160µ. High Flux cores are available in sizes identical to MPP cores. Magnetics XFLUX distributed air gap cores are made from 6.5% silicon iron powder. A true high temperature material, with no thermal aging, XFLUX offers lower losses than powder iron cores and superior DC Bias performance. The soft saturation of XFLUX material offers an advantage over ferrite cores. XFLUX cores are ideal for low and medium frequency chokes where inductance at peak is critical. MPP THINZ are extremely low height (<1 mm) self-shielded power inductor cores, allowing finished inductor heights in the 1.5 mm to 2 mm range. THINZ come in 5 sizes with O.D.s ranging from 3.05 mm through 78 mm and four permeabilities: 125µ, 160µ, 200µ and 250µ.
